UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 Jaime Loichinger, Director Office of Federal Agency Programs Advisory Council on Historic Preservation 401 F Street NW, Suite 308 Washington, DC 20001-2637
SUBJECT:
NOTIFICATION OF ADVERSE EFFECT FINDING FOR THE TERRAPOWER KEMMERER POWER STATION UNIT 1 CONSTRUCTION PERMIT REVIEW IN LINCOLN COUNTY, WYOMING (DOCKET NUMBER: 50-613)
Dear Jaime Loichinger:
The U.S. Nuclear Regulatory Commission (NRC) is soliciting input on aspects of a proposed licensing action in Kemmerer, Lincoln County, Wyoming and providing notification about an upcoming Tribal information workshop. The NRC staff is reviewing a construction permit (CP) application submitted by TerraPower, LLC (TerraPower), on behalf of US SFR Owner, LLC, a wholly owned subsidiary of TerraPower, for the proposed Kemmerer Power Station Unit 1. The application was submitted to the NRC by letter dated March 28, 2024 (Agencywide Documents Access and Management System (ADAMS) Package ML24088A059), pursuant to Title 10 of the Code of Federal Regulations (10 CFR) Part 50, Domestic Licensing of Production and Utilization Facilities. An environmental report was included as part of the application (ML24088A072). These documents may be obtained online in the NRCs ADAMS Public Documents collection at https://www.nrc.gov/reading-rm/adams.html. To begin the search, select Begin Web-based ADAMS Search. For problems with ADAMS, please contact the NRCs Public Document Room (PDR) reference staff at 1-800-397-4209, at 301-415-4737, or by email to PDR.Resource@nrc.gov. The application and additional information is also available on the NRCs public website at https://www.nrc.gov/reactors/new-reactors/advanced/who-were-working-with/applicant-projects/terrapower.html.
The purpose of this letter is three-fold:
Solicit input on the adequacy of a Class III cultural resources report and notify you of NRCs determination that the proposed action would result in adverse effects on historic properties; Provide information on the preparation of a memorandum of agreement (MOA) to resolve adverse effects; and Provide notification about an upcoming Tribal information workshop planned for February 25, 2025.
All activities described within this letter are expected to be conducted within the set schedule for the Kemmerer Power Station Unit 1 CP review and are consistent with the NRC mission, which February 4, 2025

is to protect public health and safety and advance the nations common defense and security by enabling the safe and secure use and deployment of civilian nuclear energy technologies and radioactive materials through efficient and reliable licensing, oversight, and regulation for the benefit of society and the environment.
Project Overview The proposed facility, if permitted, would be constructed within the Kemmerer Power Station Unit 1 site in Kemmerer, Lincoln County, Wyoming (see Enclosure 1). As part of its review, the NRC staff is preparing an environmental impact statement (EIS) on the proposed action of whether to issue a CP for the facility, as provided by 10 CFR 51, Environmental Protection Regulations for Domestic Licensing and Related Regulatory Functions, the NRCs environmental protection regulations that implement the National Environmental Policy Act of 1969, as amended (NEPA). In accordance with Title 36 of the Code of Federal Regulations (36 CFR) Part 800, Protection of Historic Properties, Paragraph 800.8(c), the NRC staff is using the NEPA process to comply with Section 106 of the National Historic Preservation Act of 1966, as amended, in lieu of the procedures set forth in 36 CFR 800.3 through 800.6. The EIS will include identification of historic and cultural resources and historic properties, an analysis of potential effects of the proposed action, including potential effects on historic and cultural resources and historic properties, and the NRC staffs determination. The U.S. Department of Energy (DOE) Office of Clean Energy Demonstrations (OCED) serves as a cooperating agency for the environmental review (ML23213A147), and the NRC is the lead Federal agency for the environmental review.
As described by correspondence sent in June 2024 (ML24114A087 and ML24114A079), the proposed Kemmerer Power Station Unit 1 would be located west of the North Fork Little Muddy Creek in Lincoln County, Wyoming. The proposed site is approximately 3.8 miles southeast of the Naughton Power Plant and approximately 3 miles south of the City of Kemmerer, Wyoming.
The site comprises approximately 290 acres and is located on undeveloped land. TerraPower has proposed the construction of transmission and water supply lines approximately 6 miles in length to support Kemmerer Power Station Unit 1. The facility is planned to be a pool-type reactor that uses liquid sodium as the coolant instead of water.
The NRC staff has defined the direct and indirect area of potential effects (APE) for this CP licensing action as the Kemmerer Power Station Unit 1 site and its immediate environs and the proposed transmission and water supply lines, which may be directly or indirectly impacted by land-disturbing and building activities associated with the construction of the proposed facility. is a map of the APE.
Class III Report and Determination of Adverse Effects Consistent with 36 CFR 800.2(c)(2)(ii) and 36 CFR 800.8(c)(1), the NRC staff is ensuring that Indian Tribes that might attach religious and cultural significance to historic properties in the APE are afforded the opportunity to identify their concerns, provide advice on the identification and evaluation of historic properties, including those of traditional religious and cultural importance, and participate in the resolution of any adverse effects on such properties.
As documented by TerraPower in its environmental report and supported by a recently completed Class III Cultural Resources Report (Enclosure 2), the currently planned construction activities at Kemmerer Power Station Unit 1, including for the transmission and water supply

lines, would have adverse effects on two historic properties: 48LN740 and 48LN8940. As noted below, these adverse impacts will be mitigated through the development of an MOA.
48LN740. This historic property is a multi-component prehistoric and historic-era artifact scatter with both surface and sub-surface contexts (see figure 6 of Enclosure 2). Identified artifacts include Middle Archaic to Late Prehistoric projectile points, worked stone tools and debitage, heat-altered rocks, and various metal and glass historic items. The site is eligible for the National Register of Historic Places (NRHP) under Criterion D for its information potential.
Construction of Kemmerer Power Station Unit 1 will have an adverse effect on 48LN740 because this area will be graded, disturbed, and modified for the construction of a parking lot and other associated structures.
48LN8940. This historic property is a multi-component prehistoric and historic-era artifact scatter with both surface and sub-surface contexts (see figure 31 of Enclosure 2). Identified artifacts include one Late Archaic and one non-diagnostic projectile point, other worked stone tools and debitage, and various metal and glass historic items. The site is eligible for the NRHP under Criterion D for its information potential. Construction of the transmission and water supply lines will have an adverse effect on 48LN8940 because this area will be graded, disturbed, and modified for the construction and installation of these utilities.
The Class III cultural resources report is enclosed as Enclosure 2. Pursuant to 10 CFR 2.390, Public inspections, exemptions, requests for withholding, Enclosure 2 is withheld from public disclosure and may not be made publicly available.
Based on the above and consistent with 36 CFR 800.5, the NRC has made a finding of Adverse Effect for this undertaking. Therefore, pursuant to 36 CFR 800.6(a)(1), the NRC is herein notifying the Advisory Council on Historic Preservation (ACHP) of the Adverse Effect finding.
The NRC is not inviting the ACHP to participate in the resolution of adverse effects; however, please let us know within 15 days of receiving this notification if you will participate. The NRC is consulting with the Wyoming State Historic Preservation Officer (WY SHPO) and Tribes to develop and evaluate alternatives or modifications to the undertaking that could avoid, minimize, or mitigate adverse effects of the undertaking on historic properties in compliance with 36 CFR 800.6(a) and 36 CFR 800.8(c)(1)(v).
Draft Memorandum of Agreement If the adverse impacts cannot be sufficiently avoided or minimized, resolution of adverse effects will be considered pursuant to 36 CFR 800.6(b) and an MOA will be prepared consistent with 36 CFR 800.6(c) (see also 36 CFR 800.8(c)(4)). The NRC staff is preparing a draft MOA for consultation with the WY SHPO, Tribes, ACHP (if participating), and DOE OCED to resolve adverse effects on 48LN740 and 48LN8940. The NRC staff intends to share a preliminary draft MOA with consulting parties in March 2025.
Upcoming Tribal Information Workshop The NRC staff has scheduled a virtual workshop for consulting Tribes on February 25, 2025, to provide information on Kemmerer Power Station Unit 1, discuss the undertaking and potential impacts to historic and cultural resources, and solicit Tribal input on the MOA process and any other concerns related to the undertaking. The NRC staff has coordinated the workshop with the identified cultural resources contact for each Tribe.
